Title: Modulator-demodulator converting voltage into pulses - has integrator, comparators and low-pass filter controlling pulse shape and intervals
Inventor: LEIST HELMUT DIPL ING
IPC: H03K7/08
Filed: 1976-02-09
Abstract: The precision modulator-demodulator is used to convert a LF measured voltage (U1) into voltage pulses and vice versa. It employs an integrator (I), with its supply potential controlled via the measured voltage (U1), connected to a comparator (K1), the output of which is connected to the input of the integrator (I), to provide pulse symmetry modulation. The output of the comparator (K1) is supplied to a transmission path (S) connected at the other side to a second comparator (K2), which supplies a signal to a low-pass filter (T). The latter provides an output signal of similar configuration to the input signal (U1). Pref. the integrator (I) employs a difference amplifier (V1) with capacitive feedback, each of the comparators (K1, K2) employing a difference amplifier (V2, V3) with resistive feedback.

Title: Tooth play adjuster in pneumatic or hydraulic motors - has pressure rod which engages in gear and which is moved by pistons in tubes
Inventor: OPEL DETLEF
IPC: F15B15/08
Filed: 1976-05-21
Abstract: Tooth play adjuster in pneumatic or hydraulic swivel motors where a pressure rod in a housing engages in a gear and is axially moved by pistons in symmetrical cylinder tubes. The rod can e adjusted transversely and horizontally to its longitudinal axis to adjust the tooth flank play. Specifically, the pressure rod (3) is enclosed and axially movable by means of two cam bushes (8) symmetrically arranged in a housing (2). By timing on the pressure rod (3) and in the housing (2), they effect an adjustment of the rod transverse and horizontal to the longitudinal axis. At the same time, the cylinder tubes experience a corresponding equal adjustment transverse and horizontal to the common longitudinal axis. The discs (12) which are keyed to the cam bushes (8) and central to the bores, are axially parallel displaced by the same amount as the pressure rod (3). They transmit this displacement to the cylinder tubes (6).

Title: Laser gun for military and civil purposes - has turret head on muzzle with emitter crystal inserts
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: H01S3/09
Filed: 1976-06-25
Abstract: A laser for use as a weapon for defence against aircrafts, rockets or tanks and also for laser welding and cutting or metals, uses the light of a thermonuclear reaction to pump a solid or gaseous emitter of the ruby or CO2/iodine type. The turret head has four inserts, each with a solid emitter crystal which is tubular, in case the intended purpose is for a weapon. A protective optical system surrounds each crystal which has an outside dia. d2z and an inside dia. d1. The weapon resembles a maching gun and carries on its muzzle a turret head with four compression ignition inserts, each with an emitter crystal of tubular or cylindrical shape. This combines a fast automatic operation with a light energy which is several orders of magnitude greater than that or ordinary flash tubes.

Patent DE-2706541-A1 (DE)
Inventor: SIEGMUND WERNER
IPC: G01M3/28
Filed: 1977-02-14
Abstract: The monitoring device at a supply line (2) for a burner (5) of an oil-heating system, which serves to monitor this supply line (2) for leakages, has a two-way valve (6) which is inserted into the supply line (2) upstream of a delivery pump (3) and from which a connecting line (15) leads to a stand pipe (7). During operation of the delivery pump (3), the connecting line (15) is separated from the supply line (2) by the two-way valve (6) (Fig. 3). When the delivery pump (3) is stopped, the two-way valve (6) is operated in such a way that the supply line (2) is connected to the stand pipe (7) (Fig. 2). In the stand pipe, which is connected to a vacuum pump (9), the oil rises in accordance with the prevailing vacuum. In the event of a leak, air passes into the supply line (2), which in turn leads to an increase in pressure in the stand pipe (7). This increase in pressure is detected by means of a pressure-dependent switch (12). By the leakage monitoring being restricted to the stoppage times of the delivery pump (3), because during its operation no oil runs out of the supply line (2) on account of the suction effect, the monitoring device can be of simple configuration and can be fitted in particular in existing systems. <IMAGE>

Title: Drive for distributor in IC engines - has eccentric housing facilitating change of transmission ratio for different design engines
Inventor: MESSORI PIER PAOLO
IPC: F16H57/021
Filed: 1977-05-25
Abstract: The drive for distributor in IC engine comprises an input shaft connected by gearing to an output shaft.
